SUMMARY OF THE INVENTION

One example embodiment is an arrow that includes an arrowhead, a shaft,a nock, and an internal cavity. The internal cavity includes a camera.

DETAILED DESCRIPTION

Example embodiments include methods and apparatus directed to an arrowwith one or more electronic devices.

FIG. 1 is an arrow 100 with an elongated body 110 that includes a pointor an arrowhead 120 located at one end 125 and nock 130 located at anoppositely disposed end 135. A cylindrical shaft 140 extends between thearrowhead 120 and nock 130 and includes a fletching 145 located adjacentto the nock 130. An internal cavity 150 (shown in dashed lines) extendsin one or more of the arrowhead 120, nock 130, and shaft 140.

One or more electronic devices or electronic components 160 are locatedin the internal cavity 150. The electronic devices or components can belocated in one or more of the arrowhead, the shaft, the nock, andexternal locations, such as being connected to or mounted to an exteriorsurface of the arrowhead, the shaft, and/or the nock.

The electronic devices or components 160 include, but are not limitedto, one or more of a camera and/or lens, a processor, a memory, aninterface, a display, a transmitter, a power source (such as a battery,solar cells, or a thermocoupler), an antenna, a light source (such as alight-emitting diode (LED)), an accelerometer, a photodetector (such asa photodiode), a sensor, a receiver, a transceiver, a timer, a laser, aglobal positioning system (GPS) chip, a switch, a radio-frequencyidentification (RFID) chip, a microphone, a speaker, a sound recorder, adata recorder, and other electronic device.

FIG. 2 is a partial view of an arrow 200 that includes a shaft 210 withthreads 215 and an arrowhead 220 with threads 225 that removably connectthe arrowhead to the shaft. The arrow 200 is shown with the arrowhead220 and a partial view of the shaft 210.

The arrowhead 220 includes an internal cavity 230 that encloses orhouses one or more electronic components 240 (such as one or more of theelectronic components discussed herein). By way of example, theseelectronic components include a camera 250 with a lens 255, atransmitter 260, and a battery 270. These electronic components areelectrically coupled or connected together.

A switch 275 controls power supplied from the battery 270 to the camera250 and the transmitter 260. For example, the switch is an on/off switchthat a user manually moves to activate and de-activate the battery. Asanother example, the switch activates when an end 277 of the shaft 210pushes against or touches the switch (e.g., when the shaft is connectedwith or engaged to the arrowhead). As yet another example, the switch isa channel selector for wirelessly transmitting images.

The arrowhead 220 includes an opening or window 280 through which thelens 255 is directed to capture images that are external to the arrow200. The lens 255 is positioned adjacent to or forms part of the window280, and the lens 255 can capture images through the window when thearrowhead is connected to and engaged with the shaft 210 in an assembledarrow.

The window 280 can be formed to have a sharp point to serve as a tip orpoint for the arrowhead 220. Alternatively, the window 280 can bepositioned near or adjacent to one or more sharp points, such aspositioning the window adjacent to one or more sharp points of abroadhead arrow tip.

The transmitter 260 can include an antenna 290 and/or connect to theshaft 210 of the arrow. The shaft can be conductive and function as anantenna for the transmitter 260. For instance, the shaft is made from aconductive material, such as aluminum, carbon fiber, etc. Further, thetransmitter can be separate from the camera 250 or included in or withthe camera.

FIG. 3 is an arrow 300 that includes a shaft 310 that removable connectsto an arrowhead 320. The arrow 300 is shown with the arrowhead 320 and apartial view of the shaft 310.

The shaft 310 includes an elongated cylindrical internal cavity 330 thatencloses or houses one or more electronic components 340 (such as one ormore of the electronic components discussed herein). By way of example,these electronic components include a camera 350 with a lens 355, atransmitter 360, and a battery 370. These electronic components areelectrically coupled or connected together. The lens 355 connects orcouples to the camera via a flexible cable 380 and extends to a windowor opening 390 located in the arrowhead 320. The arrowhead 320 includesa channel or hole 392 through which the flexible cable 380 inserts.

FIG. 4A is a side view of an arrow 400 that includes a shaft 410 and anarrowhead 420 shaped as a broadhead arrow tip. FIG. 4B is a top view ofthe arrow 400. Electronic components 430A are located in an internalcavity 440A (shown with dashed lines) of the arrowhead 420, andelectronic components 430B are located in an internal cavity 440B (shownwith dashed lines) of the shaft 410.

The internal cavity 440A of the arrowhead 420 encloses or houses awireless camera 450 and lens 455 that wirelessly transmit images thatthe camera captures. A base or shoulder 470 of the arrowhead 420includes an opening or window 475 through which the lens 455 capturesimages that are external to the arrow 400.

The internal cavity 440B of the shaft 410 encloses or houses a battery490. When the arrowhead 420 engages with or connects to the shaft 410,the battery 490 completes a circuit to power the camera 450. Forexample, screwing the arrowhead 420 to the shaft 410 causes electricalcontacts of the battery to engage electrical contacts of the camera 450.Unscrewing the arrowhead 420 from the shaft 410 causes the electricalcontacts to disengage.

FIG. 5 is an arrow 500 that includes a shaft 510 with an internal cavity515 (shown with dashed lines) and an arrowhead 520 with an internalcavity 525 (shown with dashed lines). The arrow 500 is shown with thearrowhead 520 and a partial view of the shaft 510.

Electronic components 530 are located in the cavity 515 of the shaft,and electronic components 540 are located in the cavity 525 of thearrowhead 520. By way of example, the electronic components 530 includea display 550, an LED 552, a sensor 554, and other electronic components556; and the electronic components 540 include a battery 560.

The shaft 510 and the arrowhead 520 engage together such that theelectronic components 530 engage or come in contact with the electroniccomponents 540. This engagement causes the battery 560 to power thedisplay 550, the LED 552, the sensor 554, and the other electroniccomponents 556.

The shaft 510 includes a clear or transparent section 570 adjacent theLED 552. Light from the LED 552 passes through the transparent section570 and provides a visual indication that shaft 510 and the arrowhead520 are properly or securely connected. The transparent section 570and/or the LED can be colored in order to provide a shooter with thevisual indication (such as providing a green light to indicate theelectronic components are properly connected and functioning and a redlight to indicate that the electronic components are not properlyconnected and functioning). For instance, this light visually indicatesthat a sensor or chip is properly functioning and that a wireless camerais on, capturing images, and transmitting these images.

The display 550 displays information from the sensor 554 and otherelectronic components 556. The display can also display informationreceived from another electronic device, such as an HPED incommunication with the arrow.

FIG. 6 is an arrow 600 that includes a shaft 610 with an internal cavity615 (shown with dashed lines), an arrowhead 620, and a nock 630 that areremovable from and connectable to the arrow 600. The cavity 615 has anelongated cylindrical shape and extends a length of the shaft 610.Electronic components 640 are located in the cavity 615 adjacent to thearrowhead 620, and electronic components 645 are located in the cavity615 adjacent to the nock 630.

A stop 650 at one end of the shaft prevents the electronic components640 from moving deeper into the cavity 615, and a stop 655 at anotherend of the shaft prevents the electronic components 645 from movingdeeper into the cavity 615. By way of example, the electronic components640 include a wireless camera, an LED, and a battery; and electroniccomponents 645 include a wireless camera, an LED, and a battery.

An LED illuminates to indicate that the battery is connected to and ispowering the wireless camera. The shaft 610, arrowhead 620, and/or nock630 can include a window and/or transparent material to enable light topass from an LED and through the arrow. For example, the nock 630 ismade from a transparent or translucent material. When the nockilluminates, a shooter is visually notified that the camera is on andfunctioning. Illumination of the LEDs can also assist the shooter intracking a flight path of the arrow and in locating the arrow after itis shot from a bow (e.g., assist a shooter in locating a lost arrow,locating an arrow shot in brush, locating an arrow at night, locating anarrow stuck in a moving target, etc.).

The shaft 610 also includes a window, hole, or opening 680 that includesa display 690. The display has a semi-circular or curved configurationthat extends fully around or partially around a body of the arrow suchthat the shape of the display emulates a shape of the body of the shaft.An exterior surface of the display is flush with the exterior surface ofthe arrow, and a smooth transition occurs from the body of the arrow tothe display. As such, the display does not protrude from the body sincesuch a protrusion could disrupt a flight path of the arrow or disruptlaunching of the arrow from a bow. The display displays informationcaptured with the electronic devices and/or information from anotherelectronic device, such as an HPED in communication with the arrow.

FIG. 7 is an arrow 700 that includes a shaft 710, an arrowhead 720, anda nock 730.

Forillustration, lens 1255A is directed to a front direction or shootingdirection of the arrow to capture images in front of the arrow, and lens12556 is directed to a back direction or opposite the shooting directionof the arrow to capture images behind the arrow.

FIG. 13 is an arrow 1300 that includes a shaft 1310, an arrowhead 1320,and a nock 1330. The arrow 1300 includes an internal cavity 1340 (shownwith dashed lines) that includes one or more electrical components 1350and includes an external body or surface 1360 that includes one or moreelectrical components 1370. The arrow includes electrical componentsthat are external to a body of the arrow and electrical components thatare internal to the body of the arrow. Example embodiments discussedherein provide examples of electrical components.

The arrow 1300 includes one or more shock absorbers 1380 that arelocated with, on, and/or adjacent to the electrical components 1350. Theshock absorber 1380 absorbs and dissipates energy from the impact of thearrow on an object in order to protect the electrical components 1350that are included with or enclosed in the arrow. Examples of a shockabsorber include, but are not limited to, a spring, foam, rubber, gel,liquid, gas, polymer, composites, and other materials or apparatus thatdampen, cushion, and/or absorb energy.

By way of example, a shock absorber is placed in front of the electroniccomponents to protect the electronic components from damage when thearrow impacts an object after flight. For instance, the shock absorberis placed inside the shaft closer to the arrowhead than the electroniccomponents that are also placed inside the shaft. As another example, ashock absorber is coated or lined along an interior surface of an arrowwith a hollow shaft, hollow arrowhead, or hollow nock. This coating orlining protects the electronic components while housed in the arrow. Asanother example, the electronic components are housed or included in apackage, and this package is covered or surrounded with the shockabsorber. The package is then placed inside of the arrow or mounted to asurface of the arrow. As another example, the electronic components aresandwiched between shock absorbers. For instance, the shock absorber ispositioned in a cylindrical hollow shaft of the arrow. The electroniccomponents are assembled into an elongated cylindrical package orassembly, and this package is positioned in the shaft next to the shockabsorber. An additional shock absorber is positioned in the shaft suchthat the shock absorbers engage each end of the package.

Some electrical components can be partially enclosed or housed in thehollow cavity of the arrow. FIG. 13 shows an electrical component 1390in which part of the electrical component is included in the internalcavity 1340, and part of the electrical component is external to theinternal cavity. A portion of the electrical component 1390 extendsthrough a hole, opening, or window 1392 in the arrow. The electricalcomponent 1390 extends through this opening to the ambient environment.Further, part of the electrical component extending to the exterior ofthe arrow can be connected or engaged with an exterior surface of thearrow, such as being connected to the shaft or arrowhead.

The electrical components 1370 are included in a housing that has apointed and/or sharp tip 1394. By way of example, the tip 1394 has aconical shape or other shape to assist the housing in passing intoand/or through the target. The tip and the housing further provide anaerodynamic shape during flight of the arrow, and this shape helps toensure that the housing does not come dislodged from the arrow uponimpacting a target.

Alternatively, the housing of electrical components can be designed todisengage from the arrow upon impacting the target. For instance, a snapfit connection connects the housing of the electrical components to thearrow. The electrical components include a GPS transmitter thattransmits a location of the housing. When the arrow passes through atarget, the housing disengages from the arrow and becomes lodged orembedded in the target so the GPS signal tracks a location of thetarget.

Consider an example in which the arrow encloses a wireless camera,transmitter, and battery. These electrical components are too large tofit completely inside of the internal cavity of the arrow. As such, abody of the arrow includes an opening or end through which a portion ofthese electrical components extends.

FIG. 14 is a diagram that shows electrical components 1400 that areconnectable to, removable from, and interchangeable with an arrow 1410.By way of example, these electrical components include cameras 1420(shown as camera 1, camera 2, . . . camera W), lenses 1430 (shown aslens 1, lens 2, . . . lens X), power sources or batteries 1440 (shown asbattery 1, battery 2, . . . battery Y), and other electrical components1450 (shown as electrical comp 1, electrical comp 2, . . . electricalcomp Z). Example embodiments discussed herein provide examples ofelectrical components.

Consider an example in which an arrow includes a wireless camera and alens. After the arrow impacts a target, the lens of the camera becomesscratched or damaged. The damaged lens is removed from the camera andreplaced with a new lens.

Consider an example in which an arrow includes a battery that powers oneor more electrical components. After a period of time, the battery losesits charge or becomes weak. The weak or depleted battery is removed fromthe arrow and replaced with a new or fully charged batter.

Consider an example in which an arrow includes a non-waterproof camera.A hunter desires to use the arrow for sports fishing. The non-waterproofcamera is replaced with a waterproof camera so the camera can captureand transmit images after being shot into the water.

Consider an example in which an arrow includes a camera with an outdoormacro-lens that is design to be used during daytime. A hunter desires touse the arrow for hunting at night. The outdoor macro-lens is replacedor exchanged with an infrared lens or a thermal lens designed fornighttime use so the camera can capture and transmit images duringnighttime. Captured images are transmitted to an HPED or a wearableelectronic device.

FIG. 15 is a method to wirelessly transmit an image from an arrow.

Block 1500 states capture an image with a camera that is enclosed insidea body of an arrow. The camera captures images that are external to thearrow while the arrow is in flight and/or after the arrow impacts atarget.

Block 1510 states wirelessly transmit the image with a transmitter to anelectronic device. For example, the images transmit to anotherelectronic device, a computer, a handheld portable electronic device(HPED), storage or memory, a server, a network, etc.

Consider an example in which the arrow has an elongated cylindrical bodywith a hollow shaft that forms an elongated cylindrical cavity. Thiscavity includes and houses a battery and a radio-frequencyidentification (RFID) chip that transmits information to an externalelectronic device. For instance, the RFID chip sends an identificationand/or location signal. The external electronic device receives thissignal and provides a global positioning system (GPS) coordinate of alocation of the arrow. This coordinate assists a shooter in locating anarrow after it is shot from a bow.

Consider an example in which the arrow includes a thermographic camerathat transmits infrared images to an HPED that is external to the arrow.These images are displayed on the HPED and assist a shooter in findingtargets at night and aligning the arrow with the target while the arrowis mounted to the bow.

Consider an example in which a camera is mounted inside a cavity of anarrow or mounted to an external body of the arrow. This camera has twolenses. A first lens is pointed to capture images from a point-of-viewof the arrowhead, and a second lens is pointed to capture images from apoint-of-view of the nock. During flight of the arrow and after impactupon a target, the arrow simultaneously transmits and/or stores imagesfrom the first and second lenses. For instance, these images appear on adisplay of an HPED so a shooter or user can see images in front of thearrow and images behind the arrow.

Consider an example in which an arrow includes a body with an internalcavity that houses a photosensor that detects ambient light external tothe arrow. The photosensor activates an electrical component or device,such as a light emitting diode (LED), in response to detecting ambientlight conditions. For instance, the photosensor activates when theambient light conditions become dark, such as activating after sunset.The LED assists the shooter in locating the arrow and automaticallyactivates after sunset.

Consider an example in which an arrow includes a body with an internalcavity that houses a sensor or detector, such as a light dependentresistor, a light sensitive switch, photosensor, photodiode,photodetector, piezoelectric sensor, or other device that measurestemperature, pressure, strain, light, acceleration, location, or force).This sensor or detector activates and provides a signal to anotherelectrical device. For instance, a piezoelectric sensor senses impact ofthe arrow on a target and activates an RFID chip to transmit a locationsignal to an HPED or activates an LED in a nock of the arrow toilluminate. Further, the sensor or detector can be positioned in thearrow in order to activate when the arrow becomes embedded in a targetor passes through the target. For instance, when the arrowhead isembedded inside of a target or passes through the target, activate anLED, an RFID chip, or a GPS chip. As another example, activation of theelectrical component can occur when the arrow is launched from the bow.For instance, the sensor or detector senses or determines accelerationof the arrow from the bow and automatically triggers or activates theelectrical component or device.

Consider an example in which an arrow has a nock and arrowhead thatremovably connect to and detach from a shaft of the arrow with asnap-fit connection, tapered connection, or threaded connection. A powersource activates when the arrowhead and/or nock connects to the shaft.This power source then powers an electrical component housed in orconnected to the arrow. For instance, a battery activates when thearrowhead connects to the shaft and powers one or more of a camera, atransmitter, a receiver, an LED, an RFID chip, a GPS chip, a sensor, adetector, and another electrical component.

Consider an example in which an arrow has a nock that includes anelectrical component, such as a pressure sensor, pressure switch ormicro-switch, or touch sensor or touch switch. This electrical componentactivates when the bowstring is positioned in the nock and/or when ashooter grips opposite sides of the nock, such as when the shooterpositions the arrow in the bow or the bowstring and readies the arrowfor launch. Activation of this electrical component in turn activatesone or more of a power source, a camera, a transmitter, a receiver, anLED, an RFID chip, a GPS chip, a sensor, a detector, and anotherelectrical component.

Consider an example in which an arrow includes a translucent ortransparent nock with an internal cavity that houses or includes one ormore electrical components. These electrical components activate when ashooter grips the nock or inserts a bowstring between the grooves of thenock. For instance, a switch detects a force of the bowstring in thenock and automatically activates an LED that illuminates the nock. Thenock remains illuminated for a set period of time or until turned off.

Consider an example in which the arrow has a nock that illuminates. Ahunter shoots an animal or prey (such as a deer) that runs or hidesafter being hit with the arrow. Illumination of the nock provides thehunter with a visible location of the arrow. Light from the nock wouldassist the hunter in finding the arrow and/or animal, especially if theambient light were low such as at dusk, dark, deep woods, or heavybrush.

Consider an example in which the arrow has a tracking device embedded orhoused inside a body of the arrow, such as a GPS chip, an RFID chip, atransmitter, or a tiny tracking device. A hunter shoots an animal orprey (such as a deer) that runs or hides after being hit with the arrow.Alternatively, the hunter misses and loses the arrow in the woods orheavy brush. The tracking device automatically activates upon impact ofan object or launch from the bow. An HPED receives a signal from thetracking device and assists the hunter in locating the arrow. Forinstance, the HPED provides a current and real-time coordinate positionof the arrow.

Consider an example in which the arrow has a tracking device and atemperature detector or sensor embedded or housed inside a body of thearrow. A hunter shoots a warm-blooded animal or prey (such as a deer)that runs or hides after being hit with the arrow. The temperaturesensor activates the tracking device when the arrow hits thewarm-blooded animal and the sensor senses a temperature differentbetween the ambient temperature and the animal. The hunter wears awearable electronic device with a display (such as electronic glasses oran electronic watch) that receives a signal from the tracking device andassists the hunter in locating the arrow.

Consider an example in which the arrow includes a window and one or moreelectronic devices enclosed in an internal cavity of a body of thearrow. These electronic devices include a display that project into orforms the window. Data captured with the electronic devices is displayedon the display. For instance, the display has a curved configurationthat forms part of an external surface of the body of the arrow.

Consider an example in which an arrow has a hollow shaft that encloses awireless camera and battery. A lens of the camera projects through abody of the shaft so the camera can capture images in front of thearrowhead. The camera transmits video images in real-time to a shooterthat wears a wearable electronic device (WED). These images display on adisplay of the WED and enable the shooter to watch the flight of thearrow as it leaves the bow, travels through the air, and impacts atarget. This video of the arrow is stored in memory for playback,transmission, editing, etc.

Consider an example in which an arrow has a first lens that capturesimages in front of the arrow, and a second lens that captures imagesbehind the arrow. After the arrow launches toward a target, the shootersees in real-time video from the first lens showing the arrowapproaching and hitting the target and real-time video from the secondlens showing the shooter immediately after shooting the arrow from thebow.

Consider an example in which an arrow has a hollow shaft that enclosestiny speakers. A shooter shoots the arrow at a target but the arrowbecomes lost. Sounds emanate from the speakers and assist the shooter inlocating the arrow. For instance, the arrow repeatedly emits a beepingsound or other audible sound. Further, the arrow can communicate withthe shooter through an HPED, WED, or other electronic device. Theseelectronic devices can control which sounds emanate from the speakers(e.g., a user selecting from a list of different sounds to emanate atthe arrow). Additionally, the shooter can speak into a microphone at theelectronic device and have these sounds transmitted to the arrow andspeakers in real-time.

Consider an example in which several hunters are hunting together in agroup. Each hunter has a bow with an arrow having a wireless camera. Thehunters wear a WED that enables them to see real-time images that arebeing captured from each of the arrows of each of the hunters. Forinstance, hunter A views video being captured from his own camera, thenswitches or also views video being captured from hunter B and hunter C.

The optical lens can be different types and interchangeable with thecamera. By way of example, the lens include, but are not limited to, amacro lens, micro lens, a zoom lens, a process lens, an infrared lens,an ultraviolet lens, a wide-angle lens, etc. Further, a single arrow caninclude multiple different lenses (e.g., an arrow that includes a macrolens and an infrared lens).

In example embodiments, the lens can be directed to a front direction orshooting direction of the arrow. As such, the lens captures images ofthe flight path or trajectory path after the arrow is launched from thebow. For example, the lens is pointed to align with the arrowhead, andthe camera captures images of the flight path of the arrow and itstarget. The lens can also be directed to a back direction that isopposite to the shooting direction of the arrow. As such, the lenscaptures images away from the flight path or trajectory path after thearrow is launched from the bow. For example, the lens is pointed toalign with the nock, and the camera captures images that occur behindthe arrow as the arrow flies to the target (e.g., captures images of theshooter that just shot the arrow). Captured images are wirelesslytransmitted to another electronic device, such as a computer or handheldportable electronic device (HPED). These images can also be stored inthe camera.

The window is formed from or includes one or more of metal, glass,ceramic, polymer, composites, transparent material or coating, and/ortranslucent material or coating. As one example, the window is formedfrom a high-strength transparent material. For instance, an opticallyclear strong transparent polymer glass composite includes one or morepolymers combine with glass fibers to form a fiber glass reinforcedplastic (FRP) with an optical transparency of clear glass.

Such a composite is optically clear, impact resistant, lightweight,strong, and inexpensive to manufacture. A glass ribbon-reinforcedtransparent polymer composite provides low distortion, good opticaltransparency, and mechanical strength over a wide range of temperatures.As another example, the window is formed from one or more layers ofpolycarbonate and glass. As another example, the window is formed from atransparent aluminum-based ceramic, such as aluminum oxynitride.

The addition of electronic components can alter a forward of center(FOC) point or balance point of the arrow. The electronic components canbe positioned inside the cavity at a location that minimizes a change tothe FOC point or balance point. Additionally, this additional weight canbe offset or countered by changing a design of the shaft, providing someelectronic components on one side of the FOC point or balance point andother electronic components on another side of the FOC point or balancepoint, adding weight to an end of the shaft, reducing weight of thearrowhead, etc.

The electronic components can fit inside and be removable from differentportions of the arrow, such as fitting inside the arrowhead, the shaft,and/or the nock. The electronic components can also be integrally formedwith and not removable from the different portions of the arrow, such asbeing integrally formed with the arrowhead, the shaft, and/or the nock.

The electronic components can be shaped as a portion of the arrow orhoused in an assembly that emulates a size and shape of the arrow. Forexample, one or more electronic components are housed in an assemblythat has a housing or structure that is sized and shaped as a nock forthe arrow. This nock removably connects to or engages with the shaft ofthe arrow. As another example, one or more electronic components arehoused in an assembly that has a housing or structure that is sized andshaped as an arrowhead for the arrow. This arrowhead removably connectsto or engages with the shaft of the arrow. As another example,electronic components (such as a wireless camera, lens, and battery) arehoused in an assembly that has an elongated cylindrical shape. Thiscylindrical assembly has a diameter smaller than an inner diameter of ashaft of the arrow. As such, the cylindrical assembly slides into theshaft of the arrow and is housed therein.

The electronic components can be made and/or sold separately from thearrow or components of the arrow. Alternatively, the electroniccomponents can be made and/or sold with the arrow or with components ofthe arrow. For example, an arrowhead is made and assembled to include awireless camera. Users purchase the arrowhead with the camera alreadyinstalled in or with the arrowhead. As another example, a nock is madeand assembled to include an electronic component (such as an LED). Userspurchase the nock with the electronic component already installed in orwith the nock.
